The best thing you can do is phone, find out when they parade, and turn up to see what you think for yourself. If you join them, you may well get to drive a tiny tank and wear a natty red hat. Whats not to like?
For someone starting out though it is a big commitment and there was a stage when they were having to train as recruits with 4 PARA too. Amazingly many failed selection but had not attempted P Coy so had to do it to then join 4 PARA, get some experience then try again.
